This invention relates to a low-temperature lead-free overglaze pigment, which is composed of lead-free pigment 8-30 wt.%, and lead- and cadmium-free flux 70-92 wt.%. The flux is composed of: SiO2 30-60 wt%, B2O3 5-35 wt.%, Al2O3 1.5-15 wt.%, K2O 1.5-10 wt.%, Na2O 1.5-10 wt.%, Li2O 0-8 wt.%, ZnO 0-15 wt.%, CaO 0-5 wt.%, CoO 0-10 wt.%, BaO 0-5 wt.%, MgO 1-5 wt.%, ZrO2 0-10 wt.%, SnO2 0-10 wt.%, and TiO2 0-5 wt.%. The low-temperature lead-free overglaze pigment has such advantages as no toxic or side effects, compact structure, high chemical stability, low baking temperature, beautiful color, high resistance to acid and base, appropriate thermal expansion coefficient, good luster, good decoration effect, and simple preparation.
